Notable changes

CONJS-284 pipeline PREPARE and EXECUTE

Previous use of connection.execute was executing PREPARE command first, read PREPARE response, then execute EXECUTE command and finally read EXECUTE response.

New implementation, when using using MariaDB server 10.2+ and with `pipelining` option enable (default value) will execute PREPARE, execute EXECUTE, then only read PREPARE response and read EXECUTE response. This permit to avoid much of the network latency.

Benchmarking results using local database (distant database would have even better result).

This improvement is for first execution of a specific query, since PREPARE is cached by default, second execution would only execute EXECUTE command

CONJS-264 validate ssl certificates using client password

In order to have SSL connections, there was 3 solutions:

Since MariaDB 11.4.1 and MDEV-31855, ssl: true is enough if password is not empty. This permit easier client configuration.
